(Well, he's actually just a computer programmer and the husband of a friend, but he IS Russian and is an expert in all sorts of interesting weaponry. Not to mention having a beautiful accent which any evil Bond villain would envy.)
I saw him at a Christmas party this Winter, and mentioned that I'd put everything I knew about illegal assault weapons into Killer Assignment.
He said, "Pfft. What you want is to write an archer." Then he leaned towards me. His voice dropped. "You see that tree way over there? I could shoot the star off the top from here. And no one would even hear me!"
So, there you have it. I was hooked. I went and took an archery class. And I changed my killer to a stealthy, silent archer. Can't say I'm able to murder any tree decorations yet, but I did manage to kill a few balloons. :)
